s10 dash lights not on and won't start

I have a 96 s-10 blazer. If I turn the key on and the dash lights don't come on, it cranks but won't start. If I turn the key off and on several times or spray electrical contact cleaner in the ignition switch the dash lights will come on and it starts right up. Just before this problem started I was driving down the road and when I took my foot off the gas it shut off. Later that day I drove 1/4 mile and the dash lights started flashing and bells started dinging. I took it home and parked it. That's when this dash light/no start problem began. Any ideas? I had the ignition switch replaced but that didn't do the trick.

Clean battery terminals and cables.Clean the grounding locations on the engine block and chassis.Check all fuses, sometimes removing them and putting them back in will help (while looking for dirty contacts and loose connections). Stop spraying cleaner on the connections! Remove the neg. battery cable and clean them with a brush! Check the egr valve and 02 sensor wires for a melted or loose connection. PM me if you need more help.

Mine does the exact opposite it turns on but doesnt shut off and the dash lights always stay on lol.

Ok, maybe I can help. I have a 1996 Chevy S-10. I had a problem with teh truck shutting off while I was running down teh road then come back on. The all of a sudden it would not start and teh dash lights didn't work but teh engine would crank. Well that has to do with teh computer. The dash lights are related to teh computer getting juice form teh battery. There are 2 fuses that go to teh computer in your fuse block. The first is on a continuous supply and teh other is on when teh ignition is turned on. Now they both should send 12 volts to teh computer when you are trying to run teh blazer. What happen to mine is teh continous source would send 12 volts but the ignition sorce would not. It ende up taht my ignition block went bad. It would send power to every thing except my cpu. YOU can test this by checking the fuse block with a an electrical tester. Pull teh fuses and turn teh key on, then check both fuse holders and see if they have power. They both should have 12 volts with eth key on, if they dont or have a reading other then say 10.5 to 12 then the ignition switch is probably bad. I paid 130.00 for mine and you have to tear teh cover off teh steering column and teh kick boards under teh dash. its a wiring harness thats located up under teh dash and held together with a 7mm bolt. The ignition block is held in with a male torx head bolt. they are really small and i had to get speical tools form sears. But check teh fuses firts and teh connectsions at teh compueter which is located in the engine compartment. Hope this helps

Well smack my azz and call me Judy. I believe we found the answer. My hubby cleaned the three relays in the glove box (you could hear them click when it was working but not when it wasn't) and the 3 relays under the hood that said they were for the air conditioning. Since they she starts 100% of the time! Thank heavens! We have tested it almost 100 times and it has yet to fail. I'll keep my fingers crossed.
